A method for determining at least one terminal for which signals transferred between the at least one terminal and a base station of a wireless cellular telecommunication network have to be relayed by a relay, the base station allocating resources of the wireless cellular telecommunication network. The method includes, executed by a management entity: receiving from the base station, information indicating to which terminal or terminals at least a part of the resources are allocated; receiving from the relay, a list of indicators of resources, and determining the at least one terminal for which signals transferred between the at least one terminal and the base station have to be relayed by the relay according to the information indicating to which terminal or terminals at least a part of the resources are allocated and to the list of indicators of resources.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for determining at least one terminal for which signals transferred between the at least one terminal and a base station of a wireless cellular telecommunication network have to be relayed by a relay, the base station allocating resources of the wireless cellular telecommunication network, the method comprising, executed by a management entity: receiving from the base station, information indicating to which terminal or terminals at least a part of the resources are allocated; receiving from the relay, a list of indicators of resources; and determining the at least one terminal for which signals transferred between the at least one terminal and the base station have to be relayed by the relay according to the information indicating to which terminal or terminals at least a part of the resources are allocated and to the list of indicators of resources.
2. The method according to claim 1 , wherein the resources are physical resource blocks and/or reference signals.
3. The method according to claim 2 , further comprising, executed by the management entity prior to the reception of the list of indicators, transferring a sounding request to the relay.
4. The method according to claim 2 , wherein the list of indicators comprises M indicators of physical resource blocks on which a characteristic of the level of received signals measured by the relay are the M highest, or the list of indicators comprises the indicators of each physical resource block on which the characteristic of the level of received signals measured by the relay is greater than a given value.
5. The method according to claim 3 , wherein the sounding request identifies at least one resource.
6. The method according to claim 5 , wherein the list of indicators comprises M indicators of physical resource blocks identified in the sounding request on which a characteristic of the level of received signals measured by the relay are the M highest, or the list of indicators comprises the indicators of each physical resource block identified in the sounding request on which the characteristic of the level of received signals measured by the relay is greater than a given value, or the list of indicators comprises M indicators of reference signals identified in the sounding request on which a characteristic of the level of received reference signals measured by the relay are the M highest, or the list of indicators comprises the indicators of each reference signal identified in the sounding request on which the characteristic of the level of received reference signals measured by the relay is greater than a given value.
7. The method according to claim 5 , wherein the list of indicators comprises characteristics of the level of received signals measured by the relay on at least a part of the physical resource blocks which are identified in the sounding request and/or characteristics of the level of at least a part of received reference signals which are identified in the sounding request.
8. The method according to claim 7 , wherein the list of indicators comprises the M highest characteristics of the level of received signals measured by the relay on the physical resource blocks identified in the sounding request or the M highest characteristics of the level of received reference signals which are identified in the sounding request or the M highest characteristics of the level of received reference signals identified in the sounding request measured by the relay on the physical resource blocks identified in the sounding request, or the list of indicators comprises characteristics of the level of received signals measured by the relay on the physical resource blocks identified in the sounding request which are greater than a given value or the characteristics of the level of received reference signals which are identified in the sounding request which are greater than the given value or the characteristics of the level of received reference signals identified in the sounding request measured by the relay on the physical resource blocks identified in the sounding request which are greater than the given value.
9. The method according to claim 1 , wherein the resources are allocated for at least a time duration and in that information indicating to which terminal or terminals at least a part of the resources are allocated indicate to which terminal or terminals at least a part of the resources are allocated for the or each time duration and the list of indicators of resources is received for one or each time duration.
10. The method according to claim 1 , wherein the information indicating to which terminal or terminals at least a part of the resources are allocated is information indicating to which terminal or terminals which experiences or experience bad data rates at least a part of the resources are allocated.
11. Method according to claim 1 , further comprising, executed by the management entity, transferring a message to the relay, the message comprising information enabling the relay to determine at least one terminal for which signals transferred between the at least one terminal and the base station have to be relayed by the relay.
12. A non-transitory computer readable medium comprising computer executable instructions or portions of code for implementing the method according to claim 1 , when the computer executable instructions or portions of code are executed on a programmable device.
13. A management entity configured to determine at least one terminal for which signals transferred between the at least one terminal and a base station of a wireless cellular telecommunication network have to be relayed by a relay, the base station allocating resources of the wireless cellular telecommunication network, the management entity comprising: means for receiving from the base station, information indicating to which terminal or terminals at least a part of the resources are allocated; means for receiving from the relay, a list of indicators of resources; and means for determining the at least one terminal for which signals transferred between the at least one terminal and the base station have to be relayed by the relay according to the information indicating to which terminal or terminals at least a part of the resources are allocated and to the list of indicators of resources.
